注(1)選擇符合閥壓差閥 - 下面的圖表內流速的關系,指的是“流量范圍
(2)對于LSVG-03EH-* - ** - **-1006(安裝螺栓:M6),壓力應為31.5兆帕。
(3)返回的排水口(Y)的壓力應為0.05兆帕或更小,并不會成為負壓。
(4)測量該值在每個閥的基礎;它可能會有所不同的實際電路/運行條件。
引腳8閥門就緒輸出集電極開路輸出電壓:zui大。 30 V,電流:zui大。 20毫安
1,對于空調整,取下保護螺絲,然后轉動微調螺絲的后面。調整完畢后,定要
..2。外部排水口的“Y”上的油箱口側,其用于干式,通常堵塞。使用的端口
油箱口邊,取出內六角圓柱頭塞(對邊寬度:5)從油箱口端和插頭的泄油口
O型圈制成氟化橡膠被要求使用磷酸酯類油液。
備安裝表面,如下所示。基本上,安裝表面的尺寸符合ISO
4401-03-02-0-94(ISO4401-AB-03-4-A-80)。安裝面應具有良好的加工光潔度,如表面
介質清潔度不高時都應在電磁閥前配裝反沖過濾閥,壓力低時,可選用直動膜片式電磁閥;
介質若是定向流通,且不允許倒流,需用雙向流通;
腐蝕性介質:宜選用塑料王電磁閥和全不銹鋼;對于強腐蝕的介 質必須選用隔離膜片式。中性介質,也宜選用銅合金為閥殼材料的電磁閥,否則,閥殼中常有銹屑脫落,尤其是動作不頻繁的場合。氨用閥則不能采用銅材。
爆炸性環(huán)境:必須選用相應防爆等級產品,露天安裝或粉塵多場合應選用防水,防塵品種。
電磁閥公稱壓力應超過管內工作壓力。
質氣,液態(tài)或混合狀態(tài)分別選用不同品種的電磁閥;
介質溫度不同規(guī)格產品,否則線圈會燒掉,密封件老化,嚴重影響壽命命;
介質粘度,通常在50cSt以下。若超過此值,通徑大于15mm時,用多功能電磁閥;通徑小于15mm時,用高粘度電磁閥。

Yuken's energy-saving hydraulic units and controllers
utilize rotational frequency control with an inverter. This
innovative configuration solves the problem of efficiency
losses suffered by induction motors operating at light
loads and ensures significant energy savings.
Extensive energy saving is possible by detecting a load
pressure with the pressure sensor and keeping the motor
rotation at the optimum level required for pressure holding.
Based on the concept above, the following two different
types of inverter-driven system and packages have been
●Energy-saving control system for hydraulic units (Energy saving controller)
For modification of existing hydraulic units to energy-saving type
●Equipped with the variable displacement piston pump
Rotational frequency control is effective for reducing power loss.
● Example of Reduction of Power Consumption
with Rotational Frequency Control
Combination of the AR22 Piston Pump and 7.5 kW Motor
